After months of negotiations, Israeli Prime Minister Yair Lapid said Sunday there are "encouraging signs" that the United States and European allies will not agree to a new nuclear deal with Iran. 

"Following the Americans, yesterday the E3 countries announced that a nuclear agreement with Iran will not be signed in the near future," Lapid said, referring to France, the United Kingdom, and Germany. 

"Israel is conducting a successful diplomatic campaign to stop the nuclear agreement and prevent the lifting of sanctions on Iran. It is not over yet. There is still a long way to go, but there are encouraging signs."

Iran started enriching uranium past the 2015 Joint Comprehensive Plan of Action's restrictions after former President Donald Trump pulled out of the deal in 2018 and reimposed harsh sanctions.

The United Nations' nuclear agency said in a report this week that Iran has uranium enriched up to 60%. 

"The Agency is not in a position to provide assurance that Iran's nuclear [program] is exclusively peaceful," the nuclear watchdog said in the report.

Iran submitted a proposal earlier this month to the European Union, which has been mediating negotiations between Tehran and Washington for months, but Secretary of State Antony Blinken said it was unproductive. 

"In past weeks, we closed some gaps. Iran had moved away from some extraneous demands, demands unrelated to the JCPOA itself," Blinken said Friday at NATO headquarters in Belgium. 

"However, the latest response takes us backwards, and we are not about to agree to a deal that doesn't meet our bottom-line requirements."
